Thiophene is considered to be aromatic, although theoretical calculations suggest that the degree of aromaticity is less than that of benzene. The "electron pairs" on sulfur are significantly delocalized in the pi electron system. As a consequence of its aromaticity, thiophene does not exhibit the properties seen for conventional sulfides. For ...

3,4-Ethylenedioxythiophene (EDOT) is an organosulfur compound with the formula C 2 H 4 O 2 C 4 H 2 S. The molecule consists of thiophene, substituted at the 3 and 4 positions with an ethylene glycolyl unit.
Poly(3-(perfluorooctyl)thiophene)s is soluble in supercritical carbon dioxide [42] [43] Oligothiophenes capped at both ends with thermally-labile alkyl esters were cast as films from solution, and then heated to remove the solublizing end groups. Atomic force microscopy (AFM) images showed a significant increase in long-range order after ...
Thieno[3,2-b]thiophene. In organic chemistry, thienothiophene is any of several compounds consisting of two fused thiophene rings. They have the molecular formula C 6 H 4 S 2. Three constitutional isomers have been synthesized: thieno[3,2-b]thiophene, thieno[2,3-b]thiophene, and thieno[3,4-b]thiophene. The other isomer features S(IV) and is ...

It is an oligomer of the heterocycle thiophene, a shorter oligomer is dithienyl, and the parent polymer is polythiophene. In the most common isomer of terthiophene, two thienyl groups are connected via their 2 positions to a central thiophene, also at the carbon atoms flanking the sulfur.
Dibenzothiophene (DBT, diphenylene sulfide) is the organosulfur compound consisting of two benzene rings fused to a central thiophene ring. It has the chemical formula C 12 H 8 S. It is a colourless solid that is chemically somewhat similar to anthracene .
